When the li-al has been we n the hinge lug (l by slipping l2 downwardly over the journals U, the ii can be turneii or swung on the OUIIlfilS a to open and close the lid. in the opening and closing movements of the liil the bosses E bear and turn on the uppei' uul luWf-r segmental cylindrical faces of the lOlll'DkllS. When the lid is in any po- Sl'tii i), exoept partially opened position about as indicated in Fig. 7, the journals 0 will wei'l'mng (he evlindricel walls of the lid bosses. it; at ne side or the other of the Thin heed is. pro ided at- I positions and for i on the lid.

nntrance slots 8, and will thus prevent the lid from being lifted off of the journals. Fig. 6 shows how the journals and bosses interlock when the lid is in the closed position. The lid, therefore, cannot be detached from the box, except by first turning it to the predetermined detaching osition and, as hereinafter explained, the c osing spring for the lid is strained to its maximum ex tent when the lid is in this detaching position and thus serves to prevent the possibility of the lid being accidentally detached.

F represents a spring nal box lid in its closed and raised or opened yieldingly resisting the opening of the lid. A coil sprin is shbwn for this purpose which surroun s it guide rod G wllch is hinged at its upper end to the journal box adjacent to the hinge lug C and is adapted to slide in it hole in an abutment g which projects inwardly from the lid. The spring bea s at one end against an enlargement or crossheud g of the rod Gr and at its other end against the abutment g This abutment is preferably rounded or convexed at the point Where the spring beers thereon to prevent binding and cramping the spring when opening and cl0sing the lid. The rod G may he pivoted at its upper end to the As shown the cross head g a: of the rod is located between ears h rejecting forwardly from the hinge lug ti and is pivoted thereto by a. pin or rivet h passing through holes in 0 id cross head and ears. The pivot pin it lC("S$-ll3l9 and can be inserted or removed n the lid is in the open position shown in 3, thus permitting the connection of the spring device to an its disconnection from the box. The arrangement of the spring and the position of the pivot for the spring rod G with reference to the axis of the hinge for the lid are such that the compression of the spring F increased by opening the lid and is at its maximum when the lid has been opened substantially to the position indicated in Fig. 7 in which the lid is adapted to be lifted ofi of the hinge lug. The spring thus acts to hold the lid firmly down on the hinge lug and prevents the accidental detachment of the lid from the box.

The hinge lug C in the construction shown is recessed at its rear side at i for the purpose of eliminating useless weight in the journal box, but the recessing of the lug is in nowisc essential to the invention. This lug C is preferably made of the some length crosswise of the box as the hinge lugs on the Master Car Builders journal boxes and is provided with a hole Ii for a hinge-pin or bolt, thus twli linu a Master Car lluildcrs" julllllill box. nd to be placed on the journal box and hinge-d thereto by the usual bolt or pin pi sing: tiu fuigxli the hole K.

the upper end for holding the jour-.

box in suitable way. substantially as C is also provided at its outer or front side with a bearing face Z for the upper end of the flat spring ordinarily employed on the Master Car Builders journal box lid. The cars it to which the spring rod is pivoted are'spaced apart far enough to permit the spring of the Master Car Builders lid to extend lJGtWBQIItllm and bear against the face Z of the hinge lug C. The construction described thus does not in any wise interfere with the substitution of a Master Car Buildcrs lid on the journal box in place of the lid B. The spring F and spring rod G are, of course, removed when a Master Car Builders lid is to be used on the box.

I claim as my invention:

The combination with a journal box, and a lid therefor, of a boltless hinge for said lid comprising 3. lug on the box provided with laterally projecting journals an having a hole extending axially through said lug and said journals, and hollow bosses on said lid which receive and are adapted to turn on said journals, said lid being adapted to be opened and closed by a. simple swinging movement about said journals, said bosses having slots through which said journals are adapted to pass when said lid is swung to a, predetermined position, set forth.

2. The combination with a journal box, 'and a lid therefor, of a boltless hinge for said lid comprising a lug on the box pro- 'vided with laterally projecting journals, and hollow cylindrical bosses in said lid which receive and are adapted to turn on said journals, .said lid being adapted to be opened and closed by a simple swin 'ng movement on said journals, said bosses aving slots 1n the lower portions of their cylindrical walls, ,through which said journals are adapted to pass when said lid is swung to a predetermined position, substantially as set forth.
